Organic production process to obtain purest quality products

Value Addition


The company is following the cryogenic powdering system in the facility in Bangalore for the powdering of superior grades of resinous wood. The temperature of the Agarwood powder in the general grinding process which does not use a cooling system can reach up to +70 degrees. Such a high temperature will reduce volatile components and heat-sensitive constituents in the Agarwood powder. This process does not damage or alter the chemical composition of the main elements in any way. The process involves cooling or chilling a material by dry ice or liquid nitrogen, and then reducing it to the size of a small particle. In the first stage, the cryogenic grinding machine powders the elements at sub-zero temperatures ranging from 0-10°C. The elements are then frozen with liquid nitrogen, as they are finally being ground to particles without disturbing the volatile and heat-sensitive constituents of the wood.


In order to get the best quality product and highest recovery, superior grades of chips are extracted in the Super Critical Fluid Extraction (SCFE) system using carbon-di-oxide as a solvent. SCFE is the process of separating one compound, that is oil, from another compound, that is Agarwood powder, using supercritical fluids as the extracting solvents. The supercritical fluid state occurs when a fluid is above its critical temperature and critical pressure when it is between the typical gas and liquid state. Manipulating the temperature and pressure of the fluid can solubilise the Agarwood mix and selectively extract it. Agarwood powder is loaded in the extraction vessel and pressurised with CO2 to dissolve. It is then transferred to a fraction collector, where the contents are depressurised, and the CO2 loses its solvating power, causing the desired material to precipitate. The condensed CO2 can be recycled for use with the next batch.

Sister concern companies of Vandurgi are engaged in the production of value added products. The main products we manufacture are Incense sticks, Agarwood Cones, Gaharu coils, beads, are some of the products we manufacture at our facilities.
